Application filed September 26, 193. Serial No. 174.713.

To all whom it may concern:

Be it known that I, WILLIAM SOBEY, a citizen of the United States, and aresident of` ro cultivators of that type in which individual 3oiic'ation.

gangs of cultivating devices, each furnished with its own pole ortongue,are connected by a transverse plank or bar whereon the driversseat is mounted.

The principal objects of my present invention are, first, to so supportthe s reader-board or seat-plank with respect to t e'cultivatorgangs asto allow for greater freedom of movement between such parte with aslittle frication as ossible; second, to provide effective means orcontrolling the movements of the cultivator appliances, theiradjustment, &c., and, third, to improve in various respects the detailsof the structure.

With these objects in view my invention consists in the features ofimprovement hereinafter described, illustrated in the accompanyingdrawings, and more particularly pointed out in the claims at the end ofthis speci- Figure 1 is a plan view of a double lister- 4cultivatorembodying my invention. Fig.2 is a view in vertical longitudinal sectionthroughl the seat-plank, parts being shown in elevation. Fig. 3 is aview in vertical crosssection on line 3 3 of Fig. 1. Fig. 4 is anenlarged view showing in side elevation one of the ground-wheels andparts connected therewith, the seat-plank being shown in crosssection.Fig. 5 is a detail View, partly in -plan and partly in horizontalsection, showlng the manner of connecting the groundwheels to theirtransverserock-shaft. Fig. 6 is a detail view in cross-section throughthe rock-shaft shown in Fig. 5, one of the shiftbars on said shaft beingshown in side elevation.

The seat-plank or spreader-board A, as is clearly shown in Figs. 1 and 2of the draw ings, extends between the gangs of cultivating devices atits opposite ends. inasmuch as the cultivating devices at each end ofthe seat-plank A are the same, a description of one will suffice forboth, like characters of reference being employed upon correspondingparts at each end of the seat-plan YThe center of the seat-plank A isshown as provided with the usual seat a and seat-stand-` ard a, and atthe base oi' the standard a a foot-rest a2 projects forwardly from theseatplank.

.Each gang of cultivating devices is shown as comprising a metal frameB, the forward ends of which are bolted, as at b, to the correspondingtongue or pole O, and between the .side bars of the frame B extends thetransverse bar b, that is preferably curved, as shown. Each of the polesor to'ngues O has bolted to its rear end a bracket 2, that is bolted, asat 3, to the back bar of the frame B, and, as shown, the tongue O isformed with a slot 4 to receive the lower edge of the transverse bar b.Through the tongue O passes a pivot-bolt 5, that passes through theforward end .of a pivot-bar D, the rear end of this bar D extending Aand being pivotall connected thereto by a through-bolt 6. he upper endof the through-bolt 6 passes through the rear' end of a strap d,extending over the seat-board, the forward end'of which is bolted, as at7, to the pivot-bar D. The upper end of the pivot-boltv 5 passes throughthe rear end of a strap 8, through the forward end of which passesadraft pin or bolt 9, that is extended through the tongue O. The bar bof the gang-frame B is preferably on the arc of a circle of which thepivot-bolt 5 is the center, and inasmuch as the pivot-bar D rests uponthe top of the transverse bar b the lateral movement of the ivot-bar Dover the bar b will be occasioned with but little friction.

So far as I am aware this invention presents the first instance in whichthe seatlplank of a double-row cultivator has been connected to theindividual gang-frames by pivot-bars supported or mounted to slide uponcross-bars of the frameaand in practice it is found that this manner ofconnecting the parts allows an ease of movement with but ittle friction.plank A extends a metal bar 10, that rests upon the upper edge of theoutside bar of the frame B, and preferably a brace-bar l1 eX- tends fromthe top of each of the bars 10 to the top side of the end of .theseat-plank A.

From each end of the seatbeneath the seat-plank IOO To the under side ofthe seat-plank adjacent each end is attached a downwardly-bent retainingstrap or bar a4, that is bolted, as at a5 and a, to the seat-plank, thisstrap or bar a4 extending below the inner side bar of the corarrangementthe cultivator-frames may shift freely to and from each other infollowing the separate rows with little friction and at the same timethe parts are securely connected together.

From the side bars of each gang-frame B depend the journal-brackets 12',upon which are revolubly mounted the ends of the transverse rock-shaft13, that is journaled in the brackets 12, and in a centraljournal-bracket 14, that is -bolted to the under side of the tongue C.Upon the shaft 13 are mountedthe depending arms 15, that carry thegroundwheels E, each of the arms 15 bein(r bent outwardly to form astub-axle 16, whereon the corresponding wheel E is journaled. Thewheel-carrying arms 15 have their upper ends provided withtubularcouplings 17, that are adjustably mounted upon the shaft 13,these couplings 17 being held in any desired yposition upon the shaft toadjust the tread of wheels E by means of set-screws 18, that passthrough the couplings 17 and bear upon the revoluble shaft 13.

It will be understood that in the usual manner carrying-wheels El ofeach cultivatorframe passes upon opposite sides of the rows of corn andthat these wheels engage the sides of the trench in which the corn isplanted, so as to properly guide the cultivating devices. These carryingwheels may be adjusted, as before described, to accommodate themselvesto trenches of different width.

Over the outer ends of each of the stubaxles 16 sits a perforated link20, that is held upon the axle by a cotter-pin 21, and to this link 20is adjustably connected a second link section or bar 22 by a bolt 22a,the upper end of this bar being bolted, as at 23, to the lower end of arock-arm or shift-bar F. end of the rock-arm or shift-bar Fis-preferably provided with a series of holes f to permit of adjustmentbetween the bar F and the upper end of the bar 22. The u per end of eachbar F isshown as formed witli a hub j", having a polygonal o eningthrough which passes the rock-shaft (see Fig. 5,) and the hub f of theshift-bar F is formed with a reduced circular portion that is journaledin a bracket The lower.

25, bolted to the rear bar of the frame B. A cotter-pin 26, passingthrough the rock-shaft G, retains the hub of the shift-bar F in properposition with respect to the bracket 25. To the rock-shaft-G isconnected a rock-arm 27, and by meansvof this rock-arm the shaft G willbe turned. The rock-arm 27 may be connected to the rock-shaft G in anysuitable manner; but I prefer to form the inner end of the rock-arm 27integral with the hub of one of the shift-bars F of each gang. The upperend of the rock-arm 27 is connected by a bar 28 to the lower end of anoperating hand-lever H, that is pivotedas at 29, to a bracket` 30,bolted to the inner side bar of the frame B and carrying at its upperedge a notched segment 31, with which engages the usual latch .7L of theoperating-lever H.

Upon the rock shaft G are adjustably mounted, by means of couplings 35,the diskcarrying arms 36, each of these arms having adjustably connectedthereto a bar 37, that carries at its inner end a disk K. The diskbars37 are adjustably connected vto the arms 36, preferably by eyebolts 37a,so that the disks may be set in any desired position. It

will be understood, of course, that by adjusting the couplings 35 alongthe rock-shaft G the disks K may be set at the required distance apart.The operating hand-levers H. whereby the gangs or cultivating devicesare controlled, are preferably bent inwardtoward the riders seat a, asclearly shown in Fig. 2 of the drawings, so that these hand-levers arewithin the easy reach of the operator.

Upon each of the rock-shafts G is adjustably mounted a bracket 40, towhich is secured the forward end of a shovel-beam M, the rear anddownwardly-curved end of this beam M carrying a shoe or shovel m.Preferably eachvof the shovel-beams M is connected to its correspondingbracket 40 by a pivot-bolt 41, passing through the end of theshovel-beam and through the bracket 40 and to permit of the adjustmentof the. shovelbeam M with respect to the bracket. The bracket is formedwith a slot 42, (see Fig. 3,) through which passes a clamp-bolt 43, thatpasses also throu h the beam. The hub of each of the brac ets 40 isformed with a polygonal seat to receive the rock-shaft G, and each hubis provided with a detachable cap 44, that is bolted to the hub, asat-45.

ln Fig. 3 the parts are shown with the cultivating devices slightlyvraised from their loperative position in the ground. In the positionshown it 4will be noted that the rock-arms f and links 22 are nearly inline. By further slightly shifting the cultivating devices to operativeposition the connecting pivot-bolt 23 between the armjl and the link 22will be carried slightly upwardly and inwardly beyond Aa line throughthe centers of `motion of the arm and link, so that the rear thrust uponthe supporting-wheels e tends to IOO IIO

IIS

amore hold or lock the cul-tivatin devices in the ground. In raising'the' cu tivating devices the pivotal point olf connection between thearm f and link 22 will be moved downwardly' and outwardly beyond a lineextending between the centers of motion of the arm and link, so that therear thrust upon the wheels will then tend to lift the cultivatingdevices.

, It should be noted that the shift-lever H is seen that the operator by manipulating the hand-levers H, or either of them, can at once raiseor lower the disks and shovels of each gang and at the same operationcan effect the corresponding rearward or forward movernentiof theground-wheels E to properly balance the cultivator and parts carriedthereby--that is to say, as the cultivating devices are shifted into andout of theground or from working to riding position the carrying-wheelsare moved backward and forward beneath the seat-plank, so that theweight of the rider will properly balance the arts, both in Working andri ing position. gy varying the point of connection between the lowerends of the shift-bars F and the upper ends of the bars 22 the shift ofthe carrying-wheels E can be modified as desired, and this I regard as afeature of importance. By thus adjust'ably connecting the Aseparaterock-shafts which carry the cultivating devices and supporting-wheelsthe relative positions of the wheels and cultivating devices maybechanged so that the machine may be accurately balanced under differentcircumstances and with riders of different weight.

It is manifest that the precise details of construction and arrangementof parts'above described may be varied without departure from the scopeof the invention.

Having thus described my invention, what I claim as new, and desire tosecure by- Letters Patent, is-
